The main forms of Poker are Draw Poker and Stud Poker. In Draw Poker, all the cards are dealt face down to the players. In Stud Poker, some of the cards are dealt face up as the betting progresses, so that all of the other players get to see a part of each player's hands.
A phylogenetic tree or evolutionary tree is a branching diagram or  tree  showing the inferred evolutionary relationships among various biological species or other entitiesâtheir phylogeny âbased upon similarities and differences in their physical or genetic characteristics.
A phylogenetic tree is the only figure in On the Origin of Species, evidence of the central importance of such trees to evolutionary biology. As discussed in Chapter 5, a phylogenetic tree is a graphical representation of the evolutionary relationships among entities that share a common ancestor.o represent such events on a phylogenetic tree, the gene phylogeny is embedded within a tree that shows the species phylogeny (Fig. 27.28). The phylogeny of the gene can be represented separately, as shown in Figure 27.28B.
